Bridging Pit Gauges

Bridging Pit Gauges
The Jr. Bridging Pit Gauge takes over where the capabilities of the standard Pit Gauges fall short, in the evaluation of large areas of corrosion. The Bridging Bar type Pit Gauges can also be used to measure dents and buckles on pipelines and shell settlement on storage tanks.

The Jr. Bridging Pit Gauge group provides the inspector with an economical alternative to the Bridging Pit Gauge System. The Jr. Bridging Pit Gauge is available in three models:

Jr. Bridging Pit Gauge (Assembles to an overall length of 13 1/2″)
Jr. Bridging Pit Gauge Plus (Assembles to an overall length of 15 1/2″)
Jr. Bridging Pit Gauge Super (Assembles to an overall length of 27″)
All models come with strong magnetic to take secure to the workpiece.

Bridging Pit Gauge System
The Bridging Pit Gauge system allows the Inspector to span or cantilever into large areas of surface corrosion to obtain accurate and consistent measurements or cross sections of pit depths. The operator can simply use the main blade or can assemble the Bridging Pit Gauge up to an overall length of 28 1/2″

The contact surfaces (Blades) of the Bridging Pit Gauges are fitted with an exclusive knife edge so they can be used on flat, ID (Convex) and OD (Concave) surfaces, where a flat or notched contact surface can introduce errors on convex surfaces.

Like the standard pit gauges, the knife edge gives the operator a clear view of the contact point and the area being inspected.

With the addition of the optional magnetic hold downs, the operator uses their width to quickly align the Bridging Pit Gauge System to the curved surface. This leaves his hands free to scan through very large areas of corrosion. This holds true when the Bridge Elements have assembled with a slight contour on the irregular surface.
